Schwalbe Ice Spiker Pro Performance Line 29 X 2.25

Schwalbe's Ice Spiker Evolution Line tire is the "turbo" of studded tires. It sports 361 spikes that bite firmly into icy roads. The tungsten carbide core of each spike is clad in weight-saving aluminum. The Ice Spiker keeps things agile and sporty while weighing in at 695 grams.

Note: In order to ensure that spikes are permanently fixed, tires should be run in for about 25 miles (40km) on asphalt, while avoiding any fast acceleration or heavy braking.
